i had used the PID tuner app for matlab and I got the proportional gain to negative (-474) but integral and derivative gains to be positive. Wat all can be done next in order to know whether my PID controller is physically realisable or not?

Why are you worried that your controller would not be physically realizable? Negative Kp does not mean controller is unstable.
